Residents across the North Carolina Piedmont spent part of Thursday night under a severe thunderstorm warning as a fast-moving cell swept over Louisburg, triggering alerts for Franklin, Granville, Halifax, Nash, Vance and Warren counties through about 10:45 p.m. Radar showed the line racing northeast at roughly 40 mph, and forecasters warned of radar-indicated wind gusts up to 60 mph, strong enough to damage roofs, siding and trees.
What forecasters saw
The National Weather Service in Raleigh issued the warning for the six counties and later allowed it to expire after the storm weakened below severe limits. According to the National Weather Service in Raleigh, radar indicated wind gusts as high as 60 mph, and officials followed the warning with a Special Weather Statement as the cell moved away from the warned area.
Safety steps and hazards
As reported by the Raleigh News & Observer, the NWS said the storm was located over Louisburg at about 9:52 p.m., moving northeast at roughly 40 mph, and urged people to "move to an interior room on the lowest floor of a building." The News & Observer also summarized NWS guidance on lightning and driving: the agency notes about 25 million lightning strikes occur in the U.S. each year and roughly 20 lightning fatalities annually, while motorists should slow down, avoid standing water and ease off the accelerator to reduce hydroplaning risk. Officials advised waiting 30 minutes after the last thunder before going back outside and to report storm damage to local emergency services.
After the advisory
The NWS follow-up message said the warning was allowed to expire at about 10:45 p.m. after the storm weakened below severe criteria. Residents across the Piedmont were urged to keep weather alerts enabled and to watch for downed branches and localized power outages into the overnight and early-morning hours.
